Semixlab TaC coated LED epi susceptor core advantages

Super high temperature resistance

TaC-coated LED epitaxial susceptors are made of high-purity tantalum carbide material, which can work stably for a long time in high-temperature environments above 1200°C. Even under the extreme temperature conditions of the MOCVD process, the coating will not crack or peel off, ensuring the uniformity and consistency of the epitaxial growth process and effectively improving product yield.

Zoo heev corrosion kuj

During the manufacturing process of LED epitaxial wafers, the susceptor needs to be exposed to corrosive gas environments such as H2 and NH3 for a long time. TaC coating has extremely strong chemical inertness and can effectively resist gas erosion and avoid impurities generated by oxidation or reaction, thereby ensuring the purity and optoelectronic performance of the epitaxial wafer.

Low thermal deformation

The thermal expansion coefficient of the TaC coating is highly matched to that of the graphite substrate, and the susceptor can maintain an extremely low thermal deformation rate even during rapid temperature rise and fall. This feature can greatly reduce the risk of epitaxial wafer warping, ensure uniform growth of the epitaxial layer, and improve product consistency.

Qhov chaw tiav siab

The susceptor surface is precisely polished, with the roughness controlled below 0.5μm, effectively reducing the defect rate during epitaxial growth. The smooth surface can also reduce the adhesion between the epitaxial wafer and the susceptor, making it easier to remove the wafer and reducing the risk of wafer breakage.

Lub neej ntev tsim

Compared with traditional graphite susceptors, TaC coating has better wear resistance and corrosion resistance, and its service life can be increased by more than 3 times. This not only reduces the frequency of consumable replacement, but also reduces process fluctuations caused by susceptor aging, which can significantly reduce production costs in the long run.
